A parallel framework for the analysis of metal-flanged rectangular-aperture arrays

Computer-aided design of horn arrays, even by using state-of-the-art electromagnetic (EM) formulations, requires a considerable numerical effort and is, therefore, an ideal candidate for parallelization. We introduce a rigorous methodology, based on Petri nets and recursive bisection, in order to migrate a standard integral equation code toward parallel multiprocessor machines, following a data-flow design and a multiple-level parallelism. Significant (quasi-linear) speed-ups are demonstrated.
